Biodiversity of Freshwater Fish in Kelekar Floodplain Ogan Ilir Regency in Indonesia

Abstract

The purpose of this study is to investigate fish biodiversity in the Kelekar floodplain. The study is explorative, with the determination of observation stations and with purposive sampling methods. Fishes were captured approximately 1.509 individuals consisting of 17 families and 24 species. The Shannon-Weiner diversity index was 2.394; 2.691; and 2.183 for station 1, 2, and 3, respectively. The Evenness index was 0.764; 0.871; and 0.806 for station 1, 2, and 3, respectively, meanwhile the highest value of Simpson’s dominance index was 0.045. The biodiversity index of the three stations was in the medium category.

The diversity of seluang fish (Danionidae, Rasbora) in the swamp waters of Cinta Marga village Ogan Ilir regency South Sumatra

“…Berdasarkan penelitian (Karlina, 2021;Utomo, 2021;Noviyanti, 2021), R. sumatrana ditemukan di Sumatera (Lumbantobing, 2014), R.tawarensis ditemukan di Danau Tawar Aceh (Muchlisin et al, 2010;Muchlisin, 2013), R. balinnes ditemukan di Bali (Hasan & Samitra, 2021). Di Indonesia, distribusi ikan-ikan famili Danionidae yakni Sungai Gedong Kabupaten Bangka (Karlina, 2021;Utomo, 2021;Noviyanti, 2021), Bali (Hasan & Samitra, 2021), Kalimantan (Roberts, 1989;Kottelat et al, 1993), Sungai Musi Kota Palembang Sumatera Selatan (Haris et al, 2018), Sungai Kelekar Kabupaten Ogan Ilir (Muslim & Syaifudin, 2022), sekitar mata air Ponggok Klaten Jawa Tengah (Diana, 2007), Hilir Sungai Sekadau Kecamatan Sekadau Hilir Kabupaten Sekadau Kalimantan Barat , Waduk Jatigede Kabupaten Sumedang Jawa Barat (Herawati et al, 2017), Waduk PB Soedirman Banjar Negara Jawa Tengah (Rukayah & Lestari, 2021), Sungai Bilah Kabupaten Labuhanbatu Sumatera Utara (Siregar & Khairul, 2022), dataran banjir sungai Rungan Kalimantan Tengah (Sulistiyarto, 2012).…”

“…Data yang diperoleh dianalisis secara deskriptif. Di Indonesia spesies R. argyrotaenia juga ditemukan di Sungai Musi, Sungai Kelekar Sumatera Selatan (Haris et al, 2018;Muslim & Syaifudin, 2022), Ponggok Klaten Jawa Tengah (Diana, 2007), Sungai Sekadau Kalimantan Barat , Waduk Jatigede Kabupaten Sumedang Jawa Barat (Herawati et al, 2017), Waduk PB Soedirman Banjar Negara Jawa Tengah (Rukayah & Lestari, 2021), Sungai Bilah Kabupaten Labuhanbatu Sumatera Utara (Siregar & Khairul, 2022), dan dataran banjir Sungai Rungan Kalimantan Tengah (Sulistiyarto, 2012). R. sumatrana juga ditemukan di Sumatra Utara (Lumbantobing, 2014), Selangor (Norfatimah et al, 2021), Penang (Leong, 1988), Semenanjung Malaysia (Shukor et al, 2008), Danau Laut Tawar, Kabupaten Aceh Tengah (Adha et al, 2023.…”

“…Menurut Abhisek et al ( 2012), ikan hias adalah ikan berwarnawarni yang menarik dengan sifat damai yang dipelihara sebagai hewan peliharaan di akuarium untuk tujuan rekreasi. Ikan seluang (Rasbora) merupakan ikan lokal perairan tawar Indonesia yang prospektif dibudidayakan sebagai ikan hias (Muslim et al, 2020).…”

DNA Authentication of Indonesian Leaffish <i>Pristolepis grooti</i> from Kelekar River and Ogan River in South Sumatra Based on <i>Cytochrome C Oxidase Subunit I (COI)</i> Gene

“…The phenotypic diversity of the two species in nature makes it difficult to determine the phenotypic comparison of the two types of fish, furthermore, the two species possibly exist in the same water (Muslim et al 2019). P. grootii has been reported as one of dominants species (C=0.05-0.014) in Kelekar floodplain, Ogan Ilir Regency (Muslim & Syaifudin 2022). Identification and characterization of leaffish are essential, as they are related to the adaptability, cultivation techniques and conservation of the leaffish in its natural habitat, which is still very limited, so thus it is important to apply a relatively easy and more accurate method to identify the species using the molecular technique, relatively.…”
